The City Council has withdrawn a grant for as much as $500,000 to a Midtown museum linked to Jona Rechnitz, the high-profile donor to Mayor de Blasio at the center of a sweeping corruption probe of the NYPD.

“Concerns were raised and the Council felt it was prudent at this time to not continue funding this program,” said Eric Koch, a spokesman for Council Speaker Melissa Mark-Viverito.

The Post reported in April that Rechnitz had helped secure $655,000 over two years from the Council to fund law-enforcement sensitivity seminars at the Simon Wiesenthal Center’s Museum of Tolerance.

Rechnitz – who sources identified as the middleman in the alleged scheme between Huberfeld and corrections union chief Norman Seabrook – is cooperating with the feds in a separate gifts-for-favors probe of top NYPD brass.

De Blasio’s 2013 campaign has said it would return donations of $4,950 each – the maximum allowed – from Rechnitz and his wife.

The real estate investor also gave $50,000 to the mayor’s non-profit political group and bundled more than $40,000 for his 2013 campaign.

A spokesman for the museum noted that its training of more than 13,000 individuals started in 2004 – well before Rechnitz got involved with the program – and that it’s not a source of profit for the institution.

“At no time was the Simon Wiesenthal Center aware of any alleged unethical or illegal activities regarding our donors. The institution is vigilant and adheres to and conforms to all city, state and federal laws,” said spokesman John McCook.

“We intend to promptly conduct our own review and determine if any further action is appropriate.”
